Concerning new formulations, I feel that there is nothing against promulgating new attitudes and theories, provided one has sufficient cause for doing so. Formulations based on insufficient data and hastily constructed are dangerous, to say the least. Prof. Freud is most careful in formulating new theories. He gathers his material for years before he puts it forth in the form of tentative theories and does not hesitate to modify them if occasion demands. Nor is it true that the Freudians ignore the work done by others. Freud and his followers give due credit to other observers, but as the Freudian mechanisms have opened up so many new fields for investigation, we naturally give most of our time to this work. That does not at all signify that we ignore everything else, as some believe. Freud himself continually urges that the psychoanalytic problems should be taken up by observers in other fields than medicine and I was, therefore, extremely pleased to hear Prof. Hall's formulations of anger. I do not believe, however, that his paper shows that we are overestimating the sexual impulse. Basically, all his mechanisms come under the heading of "Sex," as we understand it. DR. L. E. EMERSON, Boston, Mass: I wish to express my delight in President Hall's paper. It seems to me what he has done has been to show the breadth of the Freudian conception of sex. The word sex as the Freudians use it, includes all personal relations and even personality; and it is apparently in question only as to whether one is going to draw a line at one place and say everything on this side is sex and the other side personality, or whether one is going to enlarge the concept of sex to include personality. That as I understand it, is what Dr. White has also said. It seems to me the value of the sex conception lies in the fact that while it can be expanded, and is illimitable, at the same time it focuses, it does come to a point. Personalities as talked of ordinarily have no point, they are too vague. On the other hand, a man who has a mind no bigger than a pinhole is too circumscribed to be capable of understanding any very broad generalization. If one can grasp a conception that does have a center, even though no circumference, he has got hold of a very valuable generalization. DR. E. E. SOUTHARD, Boston: Dr. Jelliffe has just brought into ridicule what he terms "pinhole psychiatry;" but as I remember it, there is a technical method in psychology whereby things may be more clearly visible through a pin-hole!
